One of the clearest presentations of sed that I've seen on TH-cam. No idea why you don't have more likes! Thanks and Keep it up!

Thanks for the compliments. I also think im pretty good at explaining things but just not good with promotions hence the low viewership :-(.

@@BlueMonkey4n6 Yup! Takes so much time and effort but it's worth it.

[@jfuenmay]

I just came across your video, I think is excellent, straightforward information with great practical examples. Perhaps an early introduction to delimiters rather than late, could be useful for beginners. Keep up the good work and thank you.

[@BlueMonkey4n6]

Thanks for watching and thanks for the compliments. Good idea with the delimiters, i will put out something on that in the future.

thanks for watching and thanks for taking the time to write a comment.

I have a quick question. I noticed that when you removed the comment lines, there was one comment that remained. Is that due to the 'tab' in front of the pound sign?

[@BlueMonkey4n6]

excellent observation!! you're the first to notice. And you are absolutely correct that one comment line remained because there was a TAB before the pound sign. My regular expression was looking for lines that start with a pound sign so that line with the TAB did not match and hence left behind.

[@kahlschlag17]

when I pipe awk command into sed -i.bak ... I get sed: no input files. How can I save changes to the original input file.

[@BlueMonkey4n6]

Since sed wont be reading from a file if you are piping it with output of awk, you are really going to be doing an edit in-place. Can you give me a bit more information on exactly what you are trying to do?
